@Finn dAbuzz,
Both Hannity and Kucinich are now employed by Fox. Kucinich was recently a guest at CPAC where he and Steve King answered questions put by right wing media reporters.
As to Cohen, you should link data sources you've read.
Back in march, the NYT did a good piece on the emergence of "deep state" in right wing media sources, Breitbart foremost.
Quote:Yet to Mr. Trump’s allies and supporters, the president is giving voice to a favorite theory.
“We are talking about the emergence of a deep state led by Barack Obama, and that is something that we should prevent,” said Representative Steve King, Republican of Iowa. “The person who understands this best is Steve Bannon, and I would think that he’s advocating to make some moves to fix it.”
Mr. King cited as evidence of a thriving deep state Mr. Obama’s decision to stay in Washington after leaving the White House, a decision he said was driven by the former president’s desire to frustrate Mr. Trump’s agenda. (Mr. Obama has said he is remaining in Washington until his younger daughter, Sasha, graduates from high school in 2019.)
Mr. Trump “needs to purge the leftists within the administration that are holdovers from the Obama administration, because it appears that they are undermining his administration and his chances of success,” Mr. King said.

The utility of this set of notions for supporters of Trump is obvious. But it has utility for others as well. Russia, in its on-going attempts to sew discord in Western nations (covert propaganda campaigns in the US, European nations and re Brexit) has taken significant steps to establish this as a narrative (no small irony in them doing this). But it also has utility for domestic players who wish to discredit the institutions and operations of government, ie the Koch crowd for their own profit-taking motives.
Further, as Hofstadter documents in
The Paranoid Style in American Politics this type of notion (of very powerful, secretive agents or agencies controlling government(s) - the TriLateral Commission, the Papacy, the Jewish banking cabal, etc) has a long and rich history in America's far right and sometimes in the far left as well.
